CVE-2026-90015

A flaw was found in the Linux kernel's xHCI eXtensible Host Controller Interface driver. This vulnerability occurs when the driver processes large, fragmented USB data transfers, leading to incorrect handling of memory buffers. An attacker with local access or a malicious USB device could exploit...

CVE-2026-97430

A flaw was found in the Linux kernel's USB eXtensible Host Controller Interface xHCI driver. When the host controller is inaccessible during power management operations, such as system suspend or resume, new commands are not properly prevented from being added to the command ring. A local user...
